Abstract: Chongzuo White-Headed Langur National Nature Reserve is a typical karst landscape with abundant wildlife. In order to assess the status of large and medium-sized mammals and forest birds in the reserve, 60 infrared camera traps were set in the Tuozhu area of the reserve for continuous monitoring. Based on 4848 independent photographs collected from January 2017 to January 2018, we identified 16 mammal species and 29 bird species,including two Class Ⅰ and four Class Ⅱ state key protected animals. Based on a relative abundance index, Leopoldamys edwardsi , Melogale moschata, Tupaia belangeri, Sus scrofa and Herpestes urva were ranked as the five most abundant mammal specices.Lophura nycthemera, Pitta soror, Myophonus caeruleus and Gorsachius melanolophus were ranked as the four most common bird species. Leopoldamys edwardsi and Melogale moschata were predominantly nocturnal, while Sus scrofa , Herpestes urva , Lophura nycthemera and Pitta soror were mostly diurnal. There was no significant difference in species number and species diversity index between core zone, buffer zone and experimental zone. Our results provide preliminary data for species composition of large and medium-sized mammals and forest birds, their relative abundances, and spatial distributions in Chongzuo Reserve. This data is important for future research and protection management.

摘要: 广西崇左白头叶猴国家级自然保护区属于典型的喀斯特地貌,分布着丰富的野生动物资源。为掌握保护区内大中型兽类和林下鸟类资源现状,我们在保护区驮逐片区布设60个红外相机调查位点,于2017年1月至2018年1月开展了连续监测。共收集4848份独立有效相片,经鉴定为16种兽类和29种鸟类,包括2种国家Ⅰ级重点保护野生动物和9种国家Ⅱ级重点保护野生动物。小泡巨鼠(Leopoldamys edwardsi)、鼬獾(Melogale moschata)、北树鼩(Tupaia belangeri)、野猪(Sus scrofa)和食蟹獴(Herpestes urva)的相对多度指数分别位于兽类前五位;白鹇(Lophura nycthemera)、蓝背八色鸫(Pitta soror)、紫啸鸫(Myophonus caeruleus)以及黑冠鳽(Gorsachius melanolophus)的相对多度指数分别位于鸟类前四位。活动节律分析结果表明小泡巨鼠和鼬獾为夜行性动物,野猪、食蟹獴、白鹇和蓝背八色鸫为昼行性动物。核心区、缓冲区和实验区的物种数和多样性指数均无显著差异。本研究结果初步了解了崇左保护区内大中型兽类及林下鸟类物种组成、相对数量及空间分布,为后期的科研工作及保护管理提供了丰富的基础资料。
